jolshan opened a new pull request #11056: URL: https://github.com/apache/kafka/pull/11056
After noticing increased LISR times, we discovered a lot of time was spent synchronously flushing the partition metadata file. This PR changes the code so we asynchronously flush the files. We ensure files are flushed before appending, renaming or closing the log to ensure we have the partition metadata information on disk. Three new tests have been added to address these cases. Benchmark by @lbradstreet is included to compare the times. I will update this description after I compare trunk to this branch. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
